How can I see all thread stacks in GDB?

How can I see all thread stacks in GDB?

Use the “info threads” command to see the IDs of currently known threads. The GDB thread debugging facility allows you to observe all threads while your program runs–but whenever GDB takes control, one thread in particular is always the focus of debugging. This thread is called the current thread.

Does GDB stop all threads?

By default, GDB stops all threads when any breakpoint is hit, and resumes all threads when you issue any command (such as continue , next , step , finish , etc.) which requires that the inferior process (the one you are debugging) start to execute.

What is thread backtrace?

A backtrace is a summary of how your program got where it is. In a multi-threaded program, gdb by default shows the backtrace only for the current thread. To display the backtrace for several or all of the threads, use the command thread apply (see thread apply).

How do I see all threads in Linux?

Using the top command The top command can show a real-time view of individual threads. To enable thread views in the top output, invoke top with “-H” option. This will list all Linux threads. You can also toggle on or off thread view mode while top is running, by pressing ‘H’ key.

What does BT do in GDB?

To print a backtrace of the entire stack, use the backtrace command, or its alias bt . This command will print one line per frame for frames in the stack. By default, all stack frames are printed. You can stop the backtrace at any time by typing the system interrupt character, normally Ctrl-c .

How do I stop GDB after continue?

To stop your program while it is running, type “(ctrl) + c” (hold down the ctrl key and press c). gdb will stop your program at whatever line it has just executed. From here you can examine variables and move through your program. To specify other places where gdb should stop, see the section on breakpoints below.

What does scheduler locking do?

Set the scheduler locking mode. It applies to normal execution, record mode, and replay mode. If it is off , then there is no locking and any thread may run at any time. If on , then only the current thread may run when the inferior is resumed.

What is BT in GDB?

A backtrace is a summary of how your program got where it is. It shows one line per frame, for many frames, starting with the currently executing frame (frame zero), followed by its caller (frame one), and on up the stack. To print a backtrace of the entire stack, use the backtrace command, or its alias bt .

What is stack trace in C#?

The StackTrace property returns the frames of the call stack that originate at the location where the exception was thrown. You can obtain information about additional frames in the call stack by creating a new instance of the System. Diagnostics. StackTrace class and using its StackTrace. ToString method.

What is BT in gdb?

What is frame in gdb?

The frame contains the arguments given to the function, the function’s local variables, and the address at which the function is executing. When your program is started, the stack has only one frame, that of the function main . This is called the initial frame or the outermost frame.
